Since you have already purchased it and spent so much, I think ride it out for two weeks and hopefully it’ll work in assisting weight loss. It doesn’t seem like it but two weeks will pass pretty quickly. Your doc might have a reason for wanting you to lose weight so quickly and get you the nutrients you need. But I find it hard to understand that a doctor would recommend that at all. I think it’s pretty common knowledge that weight should not be lost so quickly. And it should be done in a way that’s sustainable. A friend of mine did the shakes for a while, lost heaps of weight, then back on it went as soon as she stopped. And she always goes back to her unhealthy way of eating. At the moment she’s overweight again and has high bp. Really not good 😕. The advice above is pretty good. It’s about getting the right amount of nutrients every day, and cutting out most sugar and processed food. A rule of thumb, anything that has a shelf life of more than 3 days shouldn’t be consumed. That’s why I go grocery shopping every couple days and try to keep my pantry empty. Momentarily I’m not doing so well, and my weight is at its highest, but we all have low points 😆. I’ve been turning to doughnuts etc for comfort. But I’m getting out of that period now. Also started belly dance as a fun way to exercise, and going walking as it’s a great way to keep healthy and slim.
So read up on info on how to eat well, and in two weeks you can start, including some walking or other fun activity 😊
